ABSTRACT

The method includes: determining, by user equipment (UE), that a first SCell has a beam failure; determining a target serving cell for transmitting a report message to a base station, the report message being configured to notify the base station that the first SCell has the beam failure; and transmitting the report message in the target serving cell. According to the embodiments of the present disclosure, the beam failure of the SCell of the UE is reported.

TECHNICAL FIELD

The present disclosure relates to the technical field of communication,and more particularly, to a method and device for reporting a beamfailure of a secondary cell (SCell) and a storage medium.

BACKGROUND

In New Radio (NR) technology, particularly when a communicationfrequency is at frequency range 2 (6 GHz or above), there is a need touse beam-based transmission and reception to ensure the coverage rangedue to fast attenuation of high-frequency channels. In the NR,beam-based transmission and reception are also needed for controlchannels, therefore, when user equipment (UE) moves or an antennarotates in direction, a reception (Rx) beam presently configured for auser of the UE to receive a Physical Downlink Control Channel (PDCCH)may have a beam failure.

Present protocol standards define reference signal (RS) resources fordetecting a beam failure. When UE detects that all RSs in these RSresources have channel quality less than threshold #1, it is indicatedthat a beam failure occurs. At this time, the UE may detect, based on anRS resource configured by a base station for determining a candidatebeam, whether RSs in the RS resource includes an RS with an L1-ReferenceSignal Received Power (L1-RSRP) meeting threshold #2; and if such an RSis included, the UE may transmit a random access preamble correspondingto the RS on a random access time-frequency resource corresponding tothe RS to implicitly notify the base station that the UE has a beamfailure in the cell and a new beam (i.e., the beam used by the RScorresponding to the random access time-frequency resource) is found.Then, the UE may detect a response message transmitted from a basestation and wait for beam recovery.

However, the above process only defines a process of reporting andrecovering a beam failure in a primary cell (PCell) of UE but noconsideration is given to how to report and recover a beam failure in asecondary cell (SCell) of the UE.

The followingdescription refers to the accompanying drawings in which the samenumbers in different drawings represent the same or similar elementsunless otherwise represented. The implementations set forth in thefollowing description of exemplary embodiments do not represent allimplementations consistent with the present disclosure. Instead, theyare merely examples of devices and methods consistent with aspectsrelated to the present disclosure as recited in the appended claims.

It is first to be noted that the sign “/” herein represents an “or”relationship. For example, “A/B” means A or B. For another example,“whether a PUCCH/PUSCH/PRACH of a first SCell is available” hereinaftershould be understood as “whether a PUCCH or a PUSCH or a PRACH of afirst SCell is available”. When this sign appears in other parts below,the specific descriptions will not be elaborated.

The application scenario of the embodiments of the present disclosure isfurther described. The following embodiments of the present disclosuremay be applied to wireless communication networks such as a 5G NRsystem, an LTE system and a Long Term Evolution Advanced (LTE-A) system,and further evolved networks thereof.

A wireless communication network may include a base station and UE. Thebase station may be a device communicating with the UE or anothercommunication station such as a relay station. The base station mayprovide a communication coverage within a special physical region. Forexample, the base station may specifically be a gNB in a 5G NR system oran Evolved Node B (briefly referred to as an ENB or eNodeB) in an LTEsystem, or, may also be another access network device providing anaccess service in the wireless communication network.

In the embodiments of the present disclosure, UE may be distributed inthe whole wireless communication network. Each UE may be static ormobile. For example, the UE may be a cellular phone, a personal digitalassistant (PDA), a handheld device, a laptop computer and other wirelesscommunication devices. The UE may also be a Machine to Machine (M2M)terminal applied to M2M communication, and may be, for example, a devicesupporting the M2M communication such as an intelligent electric meterand an intelligent household appliance. In addition, it is to be notedthat, with the constant emergence of novel Internet applications such asnew-generation Augmented Reality (AR) and Virtual Reality (VR)technologies and vehicle to vehicle communication, the scenario in whichthe wireless communication network is deployed is increasingly wide.Hence, the types of the UE may be more diverse, and there are no limitsmade thereto in the present disclosure.

Based on the above application scenario, a method for reporting a beamfailure of a SCell provided by the embodiments of the present disclosureis described below.

FIG. 1 is a flowchart showing a method for reporting a beam failure of aSCell according to an exemplary embodiment of the present disclosure.The method is applied to UE. As shown in FIG. 1, the method may includethe following operations.

In S11, it is determined that a first SCell of UE has a beam failure.

The first SCell may be any SCell of the UE.

In S12, a target serving cell for transmitting a report message to abase station is determined.

The report message is configured to notify the base station that thefirst SCell has the beam failure.

During specific implementation, in corresponding conditions, the targetserving cell may be the first SCell, or may also be a serving cell ofthe UE other than the first SCell. Conditions in which each cell of theUE can be taken as the target serving cell will be described below indetail.

In S13, the report message is transmitted in the target serving cell.

Specifically, the UE may receive configuration signaling from the basestation, and transmit a time-frequency code resource of the reportmessage through a PUCCH/PUSCH/PRACH configured by the target servingcell based on the configuration signaling.

In addition, different target serving cells may be determined inoperation S12, therefore, the report message may be transmitted indifferent ways for notifying the base station that the first SCell hasthe beam failure, which will be described below.

With the adoption of the operations of the method, when any SCell of UEhas a beam failure, a target serving cell for transmitting a reportmessage to notify the base station that the SCell has the beam failuremay be determined; and the target serving cell may specifically be aserving cell of the UE other than the SCell. In this case, the UE maytransmit, in a cross-carrier manner, the message for reporting that theSCell has the beam failure on the cell, and may further take the SCellas the target serving cell to transmit the report message under thecondition that a PUCCH/PUSCH/PRACH of the SCell is available. Therefore,it is ensured that when the SCell of the UE has the beam failure, thebase station can also be correctly notified.

The above operations will be described below in detail. FIG. 2 is aflowchart showing a method for reporting a beam failure of a SCellaccording to an exemplary embodiment of the present disclosure. As shownin FIG. 2, the method includes the following operations.

In S11, it is determined that a first SCell of UE has a beam failure.

In S121, in a condition where the first SCell belongs to an MCGcontrolled by a PCell base station, a PCell of the UE is taken as atarget serving cell for transmitting a report message to notify the basestation that the first SCell has the beam failure.

In S13, the report message is transmitted in the target serving cell.

That is, the operation S12 shown in FIG. 1 may specifically be operationS121: in a condition where the first SCell belongs to an MCG controlledby a PCell base station, a PCell of the UE is taken as a target servingcell for transmitting a report message to notify the base station thatthe first SCell has the beam failure.

FIG. 2 is merely a possible implementation manner of the embodiments ofthe present disclosure. During specific implementation, when the firstSCell belongs to an SCG controlled by a SCell base station, a PScell ofthe UE may also be taken as the target serving cell for transmitting thereport message to notify the base station that the first SCell has thebeam failure. In addition, a serving cell, configured with aPUCCH/PUSCH/PRACH, of the UE may also be taken as the target servingcell for transmitting the report message.

To sum up, the operation S13 may include that: a PCell of the UE istaken as the target serving cell, the first SCell belonging to an MCGcontrolled by a PCell base station; or, a PSCell of the UE is taken asthe target serving cell, the first SCell belonging to an SCG controlledby a SCell base station; or, a serving cell other than the first SCell,the PCell and the PSCell, of the UE, which is configured with aPUCCH/PUSCH/PRACH, is taken as the target serving cell. During specificimplementation, the target serving cell of the UE for transmitting thereport message to notify the beam failure may be pre-configured. In thisway, the UE may directly determine the target serving cell based on theconfiguration after determining that any SCell has the beam failure.

Descriptions will be made on how to specifically transmit the reportmessage in the condition where a serving cell of the UE other than thefirst SCell is taken as the target serving cell.

First manner: the report message is carried by a sequential value fortransmitting L1-RSRP of a PUCCH/PUSCH of the target serving cell, thereport message including a cell identifier of the first SCell andindication information for indicating that the beam failure occurs.

Optionally, the indication information may include identifier(s) of oneor more RSs of the first SCell and L1-RSRP of the one or more RSs, andindicate that the beam failure occurs when bit value(s) of the L1-RSRPof the RS(s), for detecting the beam failure, of the first SCell is/areall preset bit values. That is, upon the reception of the reportmessage, the base station may determine that the serving cell of the UEhas the beam failure based on the indication information, and determinethat the first SCell has the beam failure based on the serving cellidentifier.

It is to be noted that, in conventional art, an L1-RSRP absolute valueof a beam having a strongest L1-RSRP among multiple beams is indicatedby 7 bit; and L1-RSRP values of other beams are indicated by a relativevalue of the strongest L1-RSRP, the relative value of each beam beingindicated by 4 bit. The above first manner is to multiplex L1-RSRP. Abeam failure may be represented by a sequential value of bit fortransmitting the L1-RSRP. For example, in order to indicate a beamfailure of a beam, a sequential value in 4 bit, such as 0000, may be setto represent the beam failure of the beam when the beam is not a beamwith the strongest L1-RSRP. When the beam is the beam with the strongestL1-RSRP, a sequential value in 7 bit, such as 0000000, may be set torepresent the beam failure of the beam.

Second manner: the report message is carried by a sequential value forfeeding back a CQI on a PUCCH/PUSCH of the target serving cell, thereport message including a cell identifier of the first SCell andchannel quality information of the first SCell, and indicating that thebeam failure occurs when the first SCell has channel quality less than apreset threshold.

Exemplarily, the channel quality information may include a CQI value ofan RS of the first SCell for detecting the beam failure. In this way,the embodiment of the present disclosure may be designed as that whenCQI values of the RSs of the first SCell for detecting the beam failureare all less than the preset threshold, it is considered that the firstSCell has the beam failure. The condition for determining that theserving cell has the beam failure may be agreed between the UE and thebase station in advance.

Third manner: the report message is carried by a resource for an SR on aPUCCH/PUSCH of the target serving cell, the report message including acell identifier of the first SCell and indication information forindicating that the beam failure occurs.

That is, the SR resource may be multiplexed to design correspondingindication information, and both the indication information and theserving cell identifier may be taken as the report message to betransmitted to the base station, thereby notifying the base station thatthe first SCell has the beam failure. the method for multiplexingL1-RSRP in the first manner may be applied to the indication informationto indicate the beam failure with a special bit value, which will not beelaborated herein.

Fourth manner: a report message of a predefined format is transmitted ona PUCCH/PUSCH of the target serving cell, the predefined formatspecifying a bit for carrying the report message on the PUCCH/PUSCH, abit value representing a cell identifier of the first SCell, and a bitvalue representing indication information for indicating that the beamfailure occurs.

That is, both the first manner and the third manner multiplex theexisting transmission resource. In the embodiment of the presentdisclosure, a message format dedicated to indicate the beam failure mayalso be designed to transmit the report message of the predefined formaton the PUCCH/PUSCH.

Fifth manner: a preset PRACH time-frequency code resource is receivedfrom the base station, the preset PRACH time-frequency resource beingconfigured to transmit report information that the first SCell has thebeam failure; and a preset random access preamble is transmitted on thepreset PRACH time-frequency resource, to notify the base station thatthe first SCell of the UE has the beam failure.

That is, for the target serving cell configured with the PRACH, acontention free random access preamble (i.e., the above preset randomaccess preamble) may be used as the report message, and the randomaccess preamble may be transmitted on the preset PRACH time-frequencyresource, the preset PRACH time-frequency resource being a resource thatis allocated by the base station to the UE and specifically transmitsthe report message for notifying the base station that the first SCellhas the beam failure. In this way, as long as the base station receivesthe preset random access preamble on the preset PRACH time-frequencyresource, it may be considered that the first SCell has the beamfailure.

In another possible implementation manner, the UE may further use thecontention based random access preamble of the first SCell as the reportmessage, and transmit the contention based random access preamble on thePRACH time-frequency resource of the target serving cell, to notify thebase station that the first SCell of the UE has the beam failure.

Optionally, besides a serving cell of the UE other than the first SCellmay be taken as the target serving cell, in the embodiment of thepresent disclosure, in a condition where a PUCCH/PUSCH/PRACH of thefirst SCell is available, the first SCell may be determined as thetarget serving cell, and the report message may be transmitted on thePUCCH/PUSCH/PRACH of the first SCell. Exemplarily, FIG. 3 is a flowchartshowing a method for reporting a beam failure of a SCell according to anexemplary embodiment of the present disclosure. As shown in FIG. 3, themethod may include the following operations.

In S11, it is determined that a first SCell of UE has a beam failure.

In S122, whether a PUCCH/PUSCH/PRACH of the first SCell is available isdetermined.

Exemplarily, whether the PUCCH/PUSCH/PRACH of the first SCell isavailable may be determined in the following two manners.

First manner: an indication message is received from the base station,and whether the PUCCH/PUSCH/PRACH of the first SCell is available isdetermined based on the indication message.

Specifically, upon determination of a downlink reception failure of theUE in the first SCell, the base station may determine whether uplinkinformation transmitted by the UE on the PUCCH/PUSCH/PRACH of the firstSCell can be received; and if yes, it is indicated that thePUCCH/PUSCH/PRACH of the first SCell is available. In this case, thebase station may transmit the indication information through a PDCCH orPDSCH in a serving cell to notify the UE that the PUCCH/PUSCH/PRACH ofthe first SCell is available. Hence, upon reception of the indicationmessage from the base station, the UE may determine that thePUCCH/PUSCH/PRACH of the first SCell is available.

Second manner: whether reception and transmission of the UE havereciprocity is determined, and it is determined that thePUCCH/PUSCH/PRACH of the first SCell is available when the reception andtransmission of the UE do not have the reciprocity.

It is to be noted that, the reciprocity refers to that parameters of anantenna used as an information transmitting antenna and parameters of anantenna used as an information receiving antenna keep unchanged. If thereception and transmission of the UE have the reciprocity, the UE ismore likely to have an uplink failure in case of a downlink failure; andif the reception and transmission of the UE do not have reciprocity, itmay be considered that the uplink PUCCH/PUSCH/PRACH of the UE is stillavailable in case of the downlink failure.

In S123, the first SCell is taken as the target serving cell when thePUCCH/PUSCH/PRACH of the first SCell is available.

In S131, the report message is transmitted on a PUCCH/PUSCH/PRACHresource of the first SCell.

That is, the operation S12 shown in FIG. 1 may include that whether aPUCCH/PUSCH/PRACH of the first SCell is available is determined; and thefirst SCell is taken as the target serving cell when thePUCCH/PUSCH/PRACH of the first SCell is available. Meanwhile, theoperation S13 may include that the report message is transmitted on aPUCCH/PUSCH/PRACH resource of the first SCell.

Descriptions will be made on how to specifically transmit the reportmessage in the condition where the first SCell is taken as the targetserving cell.

First manner: in the condition where the PUCCH/PUSCH on the first SCellis available, the report message is carried by a sequential value fortransmitting L1-RSRP of the PUCCH/PUSCH of the first SCell, thePUCCH/PUSCH on the first SCell being available.

Optionally, the report message may include identifier(s) of one or moreRSs of the first SCell and L1-RSRP of the one or more RSs, and indicatethat the first SCell has the beam failure when bit value(s) of theL1-RSRP of the RS(s), for detecting the beam failure, of the first SCellare all preset bit values.

Second manner: in the condition where the PUCCH/PUSCH on the first SCellis available, the report message is carried by a sequential value forfeeding back a CQI on the PUCCH/PUSCH of the first SCell, the reportmessage including channel quality information of the first SCell, andindicating that the first SCell has the beam failure when the firstSCell has channel quality less than a preset threshold, the PUCCH/PUSCHon the first SCell being available.

Exemplarily, the channel quality information may include a CQI value ofan RS of the first SCell for detecting the beam failure. In this way,the embodiment of the present disclosure may be designed as that whenCQI values of RSs of the first SCell for detecting the beam failure areall less than the preset threshold, it may be considered that the firstSCell has the beam failure. The condition for determining that a servingcell has a beam failure may be agreed between the UE and the basestation in advance.

FIG. 4 is a flowchart showing a method for reporting a beam failure of aSCell according to an exemplary embodiment of the present disclosure. Asshown in FIG. 4, the method may include the following operations.

In S11, it is determined that a first SCell of UE has a beam failure.

In S124, the first SCell is taken as the target serving cell when thePRACH on the first SCell is available.

In S132, whether an RS corresponding to a new candidate beam exists isdetected in the first SCell.

In S133, if the UE detects the RS corresponding to the new candidatebeam, a corresponding random access preamble is transmitted on a PRACHtime-frequency resource of the first SCell corresponding to the RS ofthe new candidate beam, to notify the base station that the first SCellof the UE has the beam failure.

That is, in the condition where the PRACH on the first SCell of the UEis available and the UE detects the RS corresponding to the newcandidate beam, the UE may transmit the random access preamblecorresponding to the RS on the random access time-frequency resourcecorresponding to the RS, to implicitly notify the base station that theUE has the beam failure in the first SCell and finds a new beam (i.e.,the beam used by the RS corresponding to the random accesstime-frequency code resource), such that the base station may performbeam recovery on the first SCell with the new beam.

FIG. 5 is a flowchart showing a method for reporting a beam failure of aSCell according to an exemplary embodiment of the present disclosure. Asshown in FIG. 5, the method may include the following operations.

In S11, it is determined that a first SCell of UE has a beam failure.

In S122, whether a PUCCH/PUSCH/PRACH of the first SCell is available isdetermined.

When the PUCCH/PUSCH/PRACH of the first SCell is available, theoperation S123 and operation S131 are executed; and if the PUCCH, thePUSCH and the PRACH on the first SCell are all unavailable, operationS125 and operation 134 are executed.

In S123, the first SCell is taken as the target serving cell when thePUCCH/PUSCH/PRACH of the first SCell is available.

In S131, the report message is transmitted on a PUCCH/PUSCH/PRACHresource of the first SCell.

In S125, a serving cell of the UE other than the first SCell isdetermined as the target serving cell when the PUCCH, the PUSCH and thePRACH on the first SCell are all unavailable.

In S134, the report message is transmitted on the PUCCH/PUSCH/PRACHresource of the target serving cell.

The technical solutions shown in FIG. 5 are an embodiment obtained incombination with FIG. 2 and FIG. 3, and each operation may refer tocorresponding descriptions in FIG. 2 and FIG. 3 and will not beelaborated herein.

With the technical solutions shown in FIG. 5, when any SCell of UE has abeam failure, a SCell may be used as a target serving cell to transmit areport message when a PUCCH/PUSCH/PRACH of the SCell is available. Whenthe PUCCH/PUSCH/PRACH of the SCell is unavailable, a serving cell of theUE other than the SCell may be determined as the target serving cell totransmit the report message in a cross-carrier manner. Therefore, it isensured that when a SCell of UE has a beam failure, a base station canalso be correctly notified.

Further, after the UE transmits the report message to the base station,the method may further include the following operations to perform beamrecovery on the first SCell: configuration information for beammeasurement and report of the first SCell is received from the basestation; and the beam measurement is performed based on theconfiguration information and a candidate beam obtained by themeasurement is reported, the candidate beam being used by the basestation for updating a beam configuration of the first SCell. That is,the base station may obtain updated beam information by indicating theUE to perform the beam measurement and report, and allocate the updatedbeam information to the UE, thereby completing the beam recovery of thefirst SCell.
